[0027] In the field of automobile production, the luggage rack is often installed on the roof of the car body. However, the distance between the roof of the car body and the reinforced sheet metal inside the car is large. Due to the accumulation of tolerances during installation, the height of the installation point of the luggage rack is easily inconsistent, resulting in problems such as deformation of the roof of the car body. Therefore, it is usually necessary to set a support assembly between the roof of the car body and the reinforced sheet metal to support the roof of the car body.

[0028] In the related art, the support assembly includes an inner stud and an outer stud, which are screwed together by threads. When installing the support assembly, the inner stud and the outer stud are often loosened by manual pre-tightening, so that the end faces of the two are respectively pressed against the roof cover and the reinforced sheet metal of the vehicle body, and visual inspection is also required to see whether they are properly assembled. During the entire assembly process, not only is the installation space small and the assembly is difficult, but the assembly efficiency is also low, making it difficult to meet the production cycle.

[0029] See also Figure 1-Figure 3 In order to solve the problem that the existing support assembly is difficult to assemble and has low assembly efficiency, the present application provides an auxiliary installation tool 100 for a luggage rack support of an automobile. The auxiliary installation tool 100 for a luggage rack support of an automobile is used to install a luggage rack support 200 of an automobile between a roof cover (not shown) and a reinforcement sheet metal (not shown) of the automobile body, so that the luggage rack support 200 of the automobile can be supported on the roof cover and the reinforcement sheet metal. Here, the reinforcement sheet metal is arranged inside the vehicle, and it usually has a high structural strength, and can be formed by a structure such as a C-pillar upper side beam reinforcement plate.

[0030] Among them, the automobile luggage rack support 200 is as follows Figure 3 As shown, it includes an inner stud 210 and an outer stud 220, one end of the inner stud 210 is inserted into the outer stud 220 and is threadedly connected to the outer stud 220. The inner stud 210 and the outer stud 220 are both hollow sleeve structures. It should be noted that when the automobile luggage rack support 200 is placed between the vehicle body roof and the reinforced sheet metal, the axial length of the overall initial state is the shortest.

[0031] Please continue reading Figure 1 and Figure 2The auxiliary installation tool 100 for the automobile luggage rack support provided in the present application includes a tool body 10, a rotating bearing 20 and a rotating rod 30. The tool body 10 is provided with a mounting hole 101, the rotating bearing 20 is installed in the mounting hole 101 and connected to the tool body 10, the rotating bearing 20 is provided with a bearing hole 201, the rotating rod 30 passes through the bearing hole 201 and is connected to the rotating bearing 20, and the rotating rod 30 is rotatably connected to the tool body 10 through the rotating bearing 20. Among them, one end of the rotating rod 30 is used to pass through the reinforcing sheet metal and insert the inner stud 210, and is clamped with the inner stud 210 along the circumferential limit of the rotating rod 30, and the other end of the rotating rod 30 can respond to the external force to rotate relative to the tool body 10, and drive the inner stud 210 to rotate synchronously, so that the inner stud 210 moves in a direction away from the outer stud 220.

[0032] It is understandable that the tooling body 10 of the present application is arranged on the side of the reinforced sheet metal away from the vehicle roof cover. When assembling the automobile luggage rack support 200, the surface of the tooling body 10 can be first attached to the reinforced sheet metal and fixed, and the inner stud 210 is inserted into the rotating rod 30 to form a match with the inner stud 210, thereby ensuring the consistency of the assembly direction of the automobile luggage rack support 200 during the installation process and avoiding deviation. Afterwards, the rotating rod 30 drives the inner stud 210 to rotate relative to the outer stud 220, and the overall length of the automobile luggage rack support 200 is increased, so that the end face of the inner stud 210 is pressed against the vehicle roof cover, and the end face of the outer stud 220 is pressed against the reinforced sheet metal, thereby achieving reliable support of the automobile luggage rack support 200 on the vehicle roof cover, avoiding deformation of the vehicle roof cover after the automobile luggage rack is installed, and effectively improving the service life of the vehicle roof cover. In addition, the rotating rod 30 is rotatably connected to the tooling body 10 through the rotating bearing 20. Not only can the rotating bearing 20 be used to adjust the axis of the rotating rod 30 to further ensure the consistency of the assembly direction, but it is also convenient for the rotating rod 30 to rotate in response to external force. At the same time, the space where the rotating rod 30 is away from one end of the automobile luggage rack support 200 is larger, which is conducive to reducing the difficulty of operating the rotating rod 30, thereby greatly improving the assembly efficiency of the automobile luggage rack support 200.

[0033] In one embodiment, the outer stud 220 is provided with a first avoidance groove 2201, and the automobile luggage rack support auxiliary installation tooling 100 also includes a first limiting protrusion 11, which protrudes and is connected to the surface of the tooling body 10, and the first limiting protrusion 11 is used to be inserted into the first avoidance groove 2201, and is clamped with the groove wall of the first avoidance groove 2201 along the circumferential limit of the rotating rod 30.

[0034] In this way, the first limiting protrusion 11 connected to the tooling body 10 and the groove wall of the first avoidance groove 2201 on the outer stud 220 can achieve anti-rotation cooperation, so that the inner stud 210 can rotate relative to the outer stud 220, and there is no need to additionally fix the outer stud 220, thereby reducing the operation steps and helping to further reduce the assembly difficulty of the automobile luggage rack support 200.

[0035] Among them, a through hole structure which is arranged in the same shape as the first limiting protrusion 11 is opened on the reinforced sheet metal. On the one hand, the first limiting protrusion 11 can be penetrated by the through hole structure. On the other hand, the positioning stop can be achieved by the through hole structure and the first limiting protrusion 11, so that the tooling body 10 and the reinforced sheet metal are in a relatively fixed state, thereby greatly improving the installation stability of the tooling body 10.

[0036] In order to further improve the stability of the tooling body 10 during operation, in one embodiment, a second avoidance groove is opened on the reinforced sheet metal, and the automobile luggage rack support auxiliary installation tooling 100 also includes a second limiting protrusion 12, which protrudes and is connected to the surface of the tooling body 10, and the second limiting protrusion 12 is used to be inserted into the second avoidance groove and is clamped with the groove wall of the second avoidance groove along the circumferential limit of the rotating rod 30.

[0037] In this way, the second limiting protrusion 12 and the first limiting protrusion 11 cooperate with each other to effectively prevent the tool body 10 from rotating during operation, and the installation is more reliable.

[0038] In one embodiment, the tool body 10, the first limiting protrusion 11 and the second limiting protrusion 12 are an integrally formed structure to enhance the connection strength between the first limiting protrusion 11 and the second limiting protrusion 12 and the tool body 10 to avoid breakage, thereby ensuring the safety of the auxiliary installation tool 100 for the automobile luggage rack support.

[0039] In one embodiment, if Figure 1 As shown, the rotating rod 30 includes a fixed section 31 and a first anti-rotation section 32. The fixed section 31 is provided with a bearing hole 201 and is connected to the rotating bearing 20. One end of the first anti-rotation section 32 is connected to the fixed section 31, and the other end is used to insert into the inner stud 210 and anti-rotate with the inner stud 210. The cross section of the first anti-rotation section 32 is set to be polygonal.

[0040] By setting the cross section of the first anti-rotation section 32 to a polygon, the edges of the polygon can be used to achieve anti-rotation, and the overall structure is simple and easy to process.

[0041] Further, in one embodiment, if Figure 1As shown, the rotating rod 30 also includes a second stop section 33, which is arranged at one end of the fixed section 31 away from the first stop section 32 and connected to the fixed section 31. The cross section of the second stop section 33 is polygonal, and the second stop section 33 is used to drive the rotating rod 30 to rotate around its own axis in response to external force. Similarly, the second stop section 33 has a simple structure, is easy to process, and is easy to cooperate with external tools, etc., to reduce the difficulty of rotating the rotating rod 30.

[0042] Specifically, in one embodiment, the cross-sections of the first stop segment 32 and the second stop segment 33 are both hexagonal. It can be understood that the hexagonal structure is relatively common, thereby improving versatility.

[0043] Of course, in other embodiments, the cross-sections of the first stop segment 32 and the second stop segment 33 may also be triangular, quadrilateral, pentagonal or heptagonal, etc., which can be reasonably set according to actual needs.

[0044] In one embodiment, the auxiliary installation tool 100 for the luggage rack support of the automobile further includes a driving member (not shown), the output end of which is connected to the rotating rod 30, so as to drive the rotating rod 30 to rotate. In this way, the operation of driving the rotating rod 30 to rotate is more convenient, which can greatly improve the assembly efficiency of the luggage rack support 200 of the automobile.

[0045] Specifically, in this embodiment, the driving member is preferably a battery gun type torque tool, and one battery gun type torque tool can be adapted to multiple different rotating rods 30, thereby reducing costs. Of course, in other embodiments, the driving member can also be a driving motor or a hexagonal wrench.

[0046] In one embodiment, the outer wall of the rotating bearing 20 is interference-fitted with the inner wall of the mounting hole 101. In this way, the connection reliability between the rotating bearing 20 and the tooling body 10 can be ensured.

[0047] Specifically, the rotating bearing 20 can be pressed into the mounting hole 101 by a press, etc., wherein the aperture of the mounting hole 101 can be set to 9mm to 10mm, which can be adjusted according to the size of the rotating bearing 20, for example, it can be set to 9mm, 9.2mm, 9.4mm, 9.6mm, 9.8mm or 10mm, etc., which are not listed here one by one.

[0048] In one embodiment, the fixed section 31 is provided with a plurality of fixed points along its own axial direction, and the fixed section 31 can be welded and fixed to the rotating bearing 20 through any fixed point. That is, the rotating bearing 20 can be connected to any position of the fixed section 31 along the axial direction to adjust the length of the rotating rod 30 relative to both sides of the tooling body 10, so as to facilitate the connection with the automobile luggage rack support 200 or the driving member according to actual needs. Among them, the rotating bearing 20 can usually be set at a fixed point position with high versatility and fixed by welding, so as to achieve a reliable connection between the rotating rod 30 and the rotating bearing 20.

[0049] Furthermore, the cross section of the fixing section 31 may be set to be circular so as to be compatible with the inner wall of the bearing hole 201. The diameter of the rotating rod 30 is preferably set to 8 mm, and the length is preferably set to 150 mm.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
